About Naruto, didn't Naruto graduate late? Will you really be the same age as Sasuke?

You mean why Naruto said he didn't pass the graduation exam for several years and then graduated. He should be several years older than others, so how can he be the same age as a normal graduate?

I don't know. It should be that celebrities entered ninja school earlier. He doesn't have any family. Maybe he studied in ninja school since he was a child. Later, he made friends and became friends. When his friend graduated, he didn't graduate again. Later, Iruka supplemented him. He graduated in the afternoon of his friend's graduation, but he was still of the same age.

Maybe it's AB's fault, just to show that Naruto has no talent. After graduation, he didn't consider the graduation time. I don't think you should think so much.
